Didn鈥檛 get around to do Waltham Wednesday yesterday...so...doing Waltham Thursday today. Railroad grade 23j Vanguard 1908 and Dad鈥檚 solid white gold 15j Ruby...both from circa 1929. 馃憤
Rare seiko 7T59 sports 150, this is the most complicated quartz movement ever made, the first analog watch in the world to record 1/100th second and still is. It also was a very very limited production run from late 1991 to early 1993 !! A great piece of Seiko history
